IMPROVEMENT IN MACHINES FOR DRYING PAPER AND OTHER FABRICS.

The Schedule referred to in these Letters Patent and rualsingv part of the same.

bad to the accompanying drawing forming part of-v this specification, in which drawing- Figure 1 represents a longitudinal vertical section of this invention.

Figure 2 is a plan or top view of the same.

Figure 3 is a section ofa modification of the same.

Similar letters indicate corresponding parts.

This invention relates to an improvement in that class of machines for drying ,paper and other fabrics h h are principally composed of endless ropes runlug parallel to each other and supporting a series of Lransveisc rods or traverses on which the paper or other fabric to be dried is suspended in a serpentine-course, and, as the endless ropes advance slow] y, the paper or other fabric, being exposed to a draught of heated air, becomes rapidly dried.

That portion of the paper or other fabric, however, which bears uponthe traverses being exposed to the strongest heat of air in the upper part' of the room, and that portion nearest to the bottom being exposed liO lIhG heat emanating from the steam-pipes dries quicker than the intervening parts, and if the paper or other fabric is stained or tinted, it is liable to show spots or streaks at such parts which dry quickest This disadvantage I have obviated by my present invention, which consists in imparting to the traverses of the drying-machine a revolving motion in such a manner that the parts of the paper or other fabric bearing on the traverses 'are changed, and the the entire piece is dried uniformly throughout-its whole extent.

In the d'rawing- The letters A A designate twoend-less ropes, which run parallel to each other, (see fig. 2,) and are stretched over drums, to, situated at a considerable distance apart, and near to the ceiling of a room ,or apartment.

Tightening-rollers, I), serve to impart to said ropes the required tension, and to prevent the upper sections of the ropes from sagging down they are supported by a series of rollers, c. l

The ropes A A form the supports for a series of traverses, d, which rest loosely thereon, and the ends of which may be square, as shown in fig. 2, or their ends may be round, asshown in fig. 3.

When theends of the traverses are square I mount on each of said traverses one or two wheels, 0, eachwith four teeth, and, as the ends of the traverses are carried along by the motion of the endless ropes, the teeth of said wheels come in contact with stops, f, secured in the timbers B, which run parallel to the ropes and close to the same, and which form. the supports fo 'vthe axles of the drums a and of the supporting-rollers c.

The stops f may also be arranged in a vertical position by securing them in the ceiling, and they are placed at suitable distances apart, and whenever the teeth of the wheels 0 on one of the traverses come in contact with said stops, the traverse isturned a quarter revolution, and the portion of the paper or other fabric restingthereon is changed By these means every'portiou of the paper or other fabric suspended from the traverses d is uniformlyldricd, all the parts thereof being continually :changedso that the action of the heat, which is greatest above and below next to the steam-pipes, is

equally distributed, and the color ofthe fabric remains hncb an ged.

Instead of imparting to the traverses an intermittent revolving motion, however, they may receive. a

continuous revolving motion either in the same di-- rection in which the endless ropes travel, or' in the opposite direction.

In this case, the ends of the traverses are made round, and they are exposed-to the friction of a belt, 9, (see ,fig. 3,) which moves with a speed greater or lesser than that of the ropes.

By the friction of this belt the traverses are Lrevolved, and the parts of the paper or other fabric bear- 1 ing thereon are continually changed.

The revolving motion'of the traverses may also be produced by the friction of one or more elastic rollers ordrums arranged in such positions that the ends of the traverses will come in contact therewith at the proper intervals. What I claim as new, anddesire to secure by Letters Patent, is-
